avo VS sonic

I wonder whether avo could have been useful here?[1] I mention it because it came up the last time we were talking about AVX operations in go.[2]

I thought the /r/golang comments on this post were pretty useful[1]. They also introduced me to avo[2], a tool for generating x86 assembly from go that I hadn't seen before. There are some examples listed on the avo github page for generating AVX512 instructions with avo.

For writing AVX512 from scratch avo is a much better alternative.

Avo is a library that simplifies writing complex go assembly, I found it very useful to figure out how instructions map onto Go's asm syntax. But you could definitely do the translation directly, it's what c2goasm did (couldn't get it to work reliably unfortunately).

Curious if you're looking at using avo to write the assembly

You can use github.com/mmcloughlin/avo for generating the assembly use Go.

For normal and "better" mode I am using avo to generate different encoders for different input sizes, with and without Snappy compatibility. That currently outputs about 17k lines of assembly.

You could perhaps just have the Go compiler generate the assembler for your code:

go tool compile -S file.go > file_amd64.s

Then you could verify it doesn't change over time, and choose to begin maintaining by hand if it makes sense.

If you do want to go the route of rolling it yourself, I'd suggest looking into something like Avo: https://github.com/mmcloughlin/avo

If you have to go with Assembly, try Avo https://github.com/mmcloughlin/avo

Since most of the time would be spent decoding json, you could try to cut this time using https://github.com/bytedance/sonic or https://github.com/json-iterator/go, both are drop-in replacements for the stdlib, sonic is faster.

Also worth looking at https://github.com/bytedance/sonic

The article inside does not mention this.

Good morning.I hope this is not the wrong place to post… so let me introduce my first public Golang package. This is a JSON decoder called Sonnet ( https://github.com/sugawarayuuta/sonnet ) that has given faster results (at least in my environment) than Sonic - https://github.com/bytedance/sonic (which is said that it's the fastest) without the help of assembly!

JSON is a very well-known file format. It is used by everyone who does programming. However, it is also not uncommon to find problems with encoding/json and other third-party libraries. for more… (see https://github.com/sugawarayuuta/sonnet#problems-we-had )

I decided to create a new, standard library-compatible decoder that would be both easy to use and fast.

Thanks for reading, feel free to use, help, or ask questions, I look forward to hearing from you. All benchmarks and other information can be found in the link at the top.

I'd say the https://github.com/bytedance/sonic has the fastest encoder due to C and assembly optimization. (Use at your own risk.)
